2. Slide the Decline Carriage (11) onto the Bench Frame
(5). To do this, you will have to pull out on the Seat
Adjustment Knob (47). If the Knob does not pull out,
unscrew it until it is loose.
Make sure the Bench Frame (5) is oriented as
shown. The end with no bracket is cut in an
angle, and the pointed edge must be on the top
side (see inset drawing).
